Apparently, even a short summary and a hyperlink are considered to be a violation of copyright in Belgium:
A Belgian appeals court has upheld an earlier ruling that Google infringes on newspapers’ copyright when its services display and link to content from newspaper websites, according to press reports.
The search engine giant is responsible for infringing the copyrights of the papers when it links to the sites or copies sections of stories on its Google News service, the Belgian Court of Appeals said, according to a report in PC World.
Google must not link to material from Belgian newspapers, the court said, according to the report (in French). No translation of the ruling is yet available.

The newspapers argued that they were losing online subscriptions and advertising revenue because Google was posting free snippets of the stories and links to the full article on Google News.
Google’s search engine offers links to the websites it indexes but also to “cached” copies of those pages. The copies are stored on Google’s own servers.
